This investigation assessed the use of the i-gel as an alternative to local anaesthesia (LA) in insulin dependents diabetic patients undergoing cataract surgery. 60 diabetic patients were randomly assigned to receive either LA or general anaesthesia (n = 30) in combination with the i-gel (n = 30). Several parameters were monitored including mean arterial blood pressure (MBP), heart rate (HR), as well as blood glucose levels and plasma cortisol levels. Results have shown no significant difference in either blood glucose or cortisol levels in both groups. However, blood glucose level increased in both groups after induction of anaesthesia. In addition, HR and MBP increased in the LA group but not in the i-gel group. In conclusion, these results show that both LA and general anaesthesia using the i-gel are safe and do not produce a marked impact in hemodynamics, blood glucose, or cortisol levels in diabetic patients.

The objective of this study was to compare the hemodynamic disturbances and possible complications caused by the i-gel and ETT in 80 patients (ASA II) undergoing cesarean receiving general anesthesia. A range of parameters was investigated including insertion time, ease of intubation, hemodynamics (insertion and removal) and postoperative complications (sore throat, blood on device, dysphagia, regurgitation, nausea, vomiting, laryngospasm and aspiration). Findings have demonstrated that patients in the ETT group had a higher incidence of difficult intubation, 20% higher mean arterial pressure and heart rate compared to the i-gel group. The ETT group also had a higher incidence of sore throat. Thus, the i-gel constitutes a superior alternative to the ETT in patients undergoing elective surgery under general anaesthesia.

49 adult patients were randomly assigned between each device group, with fentanyl doses, hemodynamic parameters and mean arterial pressure among results taken at various points throughout the procedure. i-gel requires less anaesthetic doses in this scenario.
